Globally, per person, there is about 31 tonnes of oil (recoverable) somewhere in the Earth {{p|{{calc|oil.reserves|(tonnes per capita)(world.population)}} }}. Average production is about 1.5 kg/day per person {{p|{{calc|oil.production|(kg/day per capita)(world.population)}} }}. Rich countries consume a lot more, poor countries use a lot less. | |||

* Other uses include making thousands of different chemicals. This together adds up to only a small fraction of fossil fuel consumption, and does not contribute significantly to climate change. {{qn}} | |||
